VENTILATING- APPARATUS. I

Specification of Letters Patent.

Patented; June 5, 1917.

Application filed December 8, 1915. Serial No. 65,717.

To all whom it may concern:

Be it known that I, JAsoN E. KIRK, a citizen of the United States,residing at Christiansburg, in the county of Montgomcry and State ofVirginia, have invented a new and useful Ventilating Apparatus, of whichthe following is aspecification.

The present invention is a ventilating apparatus, designed fordelivering either fresh or warm air into a room for the comfort of theoccupants, and for withdrawing the foul air therefrom, the apparatusbeingalso useful for creating an air suction for a vacuum cleaner.

It is the object of the invention to provide a novel and improvedapparatus of the nature indicated, comprising novel means for deliveringeither fresh or warm air into the room, and novel means for withdrawingthe foul air therefrom.

It is also within the scope of the invention to improve the apparatusgenerally in its construction and details, to enhance the utility andefliciency thereof, the apparatus being comparatively simple andinexpensive in construction, and being readily installed.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed without departing from the spirit of theinvention.

The invention is illustrated in the accompanying drawings, whereinFigure 1 is a vertical median section of the apparatus, portions beingbroken away,

7 and portions being shown in elevation.

In carrying out the invention, there is.

provided a pair of centrifugal blowers 1 and 2,. embodying the unitedvertical casings 34-4, and the respective fans 5-6 rotatable within thecasings. The remote sides of the casings 3-4 are provided with centralair inlets 7-8, and the casings have a common side wall or partition 9therebetween separating the fans. A common horizontal shaft 10 for thetwo blowers is provided, the same being journaled in suitable bearings11, and projecting axially into the casings 3-4. The shaft 10 projectsthrough the partition 9' and the fans 5-6 are secured upon said shafts,the shafts being rotated by a motor, engine or other prime mover of anysuit able sort for operating the blowers at the proper velocity. Thecasing 3 has a lower outlet 12, and an outlet pipe or conduit 13 is.attached to the periphery of the casing 4 and leads to the atmosphere orother point of discharge.

An air inlet chamber 14 is secured to the outer side of the casing 3around the air inlet 7 of said casing, and is provided at that sideremote from the casing with a fresh air inlet 15 through which the shaft10 projects. In order to control the inflow of fresh air through .theinlet 15, valves 15 are disposed slidably in guides 14 carried by thechamber 14 above and below the inlet 15, said valves being disposed atopposite sides of the shaft 10 and when moved together surround saidshaft and close the inlet 15. The valves 15? can be adjusted forregulating the inlet of fresh air. A fan 16 is mounted upon the shaft-10within the housing 14 and when said shaft is rotated, the fan 16 isrotated thereby for forcing the air from the housing 14 through inlet 7into the casing 3. A similar fan can be used, if desired, for forcingair through the inlet 8 of the casing 4 into said casing.

A warm air pipe or conduit 17 is connected to the housing 14 at anysuitable point for conveying warm air from a suitable source to thehousing 14,-whereby the warm air will be delivered. into the blower 1.If the pipe 17 is independent of the inlet 15, as illustrated in Figs. 1and 3, it is preferable to provide a damper or valve 18 within the pipe17 for closing the pipe 17 when desired. Thus, when fresh air is to beadmitted into the blower 1, the valve 18 is closed, and the valves 15are opened, and

when warm air is to be used, the valves 15 to receive a'portion of theair from the "pipe are closed, while the valve 18 is opened. The pipe:17 can be arranged to admit the warm air in front of the fan 16, thesame as the fresh air. I

, In order toconvey the air from the blower 1 into the room, ahorizontal pipe 19 has one end attached tothe outer side of the casing tand projects through the wall W of the, room to the desired point withinthe room, the other end of the pipe/19 being downturned, as at 20, andhaving attached thereto, an inverted frusto-conical' head 21,constructed of sheet metal or other suitable material, and which'ishollow to communicate with the pipe 19. The sidewalls of the head 21 areprovided with outlet apertures 22, and the bottom of the head 21 hasoutlet apertures 23, said side walls being inclined whereby'the airflowing through the apertures 22 will be directed in various directionsdownwardly at an angle, while the air'flowing through the apertures 23will be directed downwardly. A frusto-conical or tapered deflector 24-has its lower larger end secured to the side walls of the head 21 abovethe bottom of said head, and the smaller end of the deflector 21projects through the upper inlet'opening of the head 21 into the end 20of the pipe 19, the smaller end of said deflector being open, asat 25,

19. The deflector 24 serves to deflect the greater portion of the airfrom the end 20 of the pipe 19 to all sides toward the apertures 22, aportion of the air flowing throughthe opening 25 into the deflectoriandthence passing through the apertures 23 downwardly. The head 21 canbeused in lieu of a chandelier, and can carry the lights whichilluminate the room. Thus, an annular support 26 can be seated uponthe'head 21 around the end 20 of the pipe 19, and the electric or otherlamps 27 can be attached to the support 26, in order that the lamps when9 air into the room.

lighted will effectively illuminate the room. By assembling the lampswith the head'2l, the head is rendered less conspicuous, and the airinlet means and illuminating means are assembled in a compact anddesirable manner. It is to be, understood that the air discharge head 21can be located at the center ofthe'room or at anyvother point thereofwhere it is desired todischarge the The pipe 19 is, connected with theblower I 1 by means of a pipe 28 having its ends,

projecting upwardly, one end beingconnected to the periphery of thecasing 3 to com- 28 into the pipe 19, and from thence into the head 21to be blown out of the apertures 22 and 23, to thus deliver either thefresh or warm air into the room in all directions below the head 21. I Vv In order to conduct the foul air from the room, a horizontal pipe 29projects into the room through the wall'W, and'extends concentricallywithin the pipe 19, the pipe- 29 being of smaller diameter, and one endof the pipe 29 is attached to the outer side of the casing 4 tocommunicate with the air inlet 8 thereof. A vertical pipe'31 is attachedto the'other end-of the pipe 29, and an annular, partition 30 is securedbetween the pipes 19 and 29 behindthe pipe 28. The upper end of the pipe31 carries a funnel 32, the pipe 31 projecting within the funnel, andsaid funnel is preferably arranged adj acentthe ceiling at a suitablepoint in the room to receive'the foul air when the'air is sucked fromthe, pipe 29 by the blower 2. The blower 1 is operable for forcing airinto the room, While the blower 2 is operable for exhausting thefoul airfrom the room, to thus establish a circulation of air within the roomfor purpose of'ventilation.

Avalve 33 carried by a rock shaft 34 journaled through one side of thefunnel .32 is seatable upon the upper end of the pipe 31 for closing thesame, the outer end vof the shaft 36L having an arm 35. I V

A valve 36 is disposed within the pipe 31 below the pipe'29, and ismounted upon a rock shaft 37 journaled through the pipe 31 and having atits outer end an'arm 38 connected by a link or rod 39 with the arm 35.The'parts are so arranged, thatwhen the valve 33 is opened, the valve 36is closed, and when the valve 36 is opened, the valve 33 is closed. Thevalve 36 is normally closed, so that the foul air is drawn into theupper end of the pipe31'.

The lower end of the pipe 31 has a spherical portion 40' upon which ismounted for oscillation in various directions the spherical enlargement41 of a depending pipe 42 to which is connected one end of a vacuumcleaner hose 43. The hose 43'can bereadily attached to and detached fromthe pipe 42,

suction will extend through the pipe 42 and hose 43 to remove the dirtand dust by air suction. c

The apparatus can be constructed, as illustrated, for individual usewith a room, or in apartments, a plurality of pipes 19 and 29 can beconnected to a single pair of blowers for ventilatinga plurality ofrooms.
